試圖將jsp提交給servlet。在web.xml映射期間出錯。將JSP映射到servlet
我
的index.jsp
<form method="POST" action="Validate">
<input type="submit" value="Submit" />
</form>
的web.xml
<servlet>
<servlet-name>validate</servlet-name>
<servlet-class>com.test.Validate</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>validate</servlet-name>
<url-pattern>/Validate</url-pattern>
</servlet-mapping>
文件夾結構
然而,當,我嘗試在服務器運行index.jsp
,我得到"server cannot be started"
錯誤時servlet映射從web.xml中刪除
錯誤去
Validate.java
package com.test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class Validate
*/
@WebServlet(description="validation", urlPatterns={"/Validate"})
public class Validate extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public Validate() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
PrintWriter out = response.getWriter();
response.setContentType("text/html");
System.out.println("validate called");
}
當我作爲服務器上運行,它的工作原理Validate.java
但是,當我作爲服務器在index.jsp
上運行,然後單擊提交。它將 重定向到http://localhost:8080/TestApp/Validate
,並且控制檯上沒有任何內容。
請分享一下'Validate.java'的代碼嗎? –
已添加Validate.java – user544079
當您點擊提交時,您正在執行HTTP POST,但您沒有在您的servlet中實施doPost方法。 – Crx
